Basic operations on finding volume

                                            Volume
Introduction:
we are familiar with many objects. Each object occupies certain amount of space. For example a stone piece occupies some space in a pond of water, sugar cubes take space in a glass of Sherbat ( Pana), Ink takes space in a pen etc. Obviously the bigger objects occupy more space than the smaller objects.

The amount or measure of the space occupied by an object is called the volume of the object.

The volume is measured in the unit like cm cube or cu cm, m cube or cu m or mm cube or cu m as per the measurement unit of the object.

The formula for finding the volume of a cube or cuboid is as follows.

Cuboid                               Length  X  breadth  X  height

Cube                                      Side  X  Side  X  Side
